为什么不应用 ImageView 高度？
我的 xml 中有两个 imageview 在线性布局中。之后我有 viewfilpper.in MotionEvent.ACTION_UP TouchEvent 我正在更改 imageview 的高度 但
((ImageView)findViewById(R.id.imgview1)).getLayoutParams().height=23;
((ImageView)findViewById(R.id.imgview1)).getLayoutParams().width=23;
((ImageView)findViewById(R.id.imgview2)).getLayoutParams().height=LayoutParams.WRAP_CONTENT;
((ImageView)findViewById(R.id.imgview2)).getLayoutParams().width=LayoutParams.WRAP_CONTENT;
在视图中，当我触摸任何 editText 字段时，就会应用更改
((ImageView)findViewById(R.id.imgview2)).invalidate();
((ImageView)findViewById(R.id.imgview2)).refreshDrawableState();
，并且通过上述语句这也不起作用，
((ImageView)findViewById(R.id.imgview1)).setLayoutParams(new LayoutParams(23,23));
((ImageView)findViewById(R.id.imgview2)).setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
我的问题没有解决
i have two imageview in my xml within linear layout.after that i have viewfilpper.in MotionEvent.ACTION_UP of TouchEvent i'm changing the height of imageview
as
((ImageView)findViewById(R.id.imgview1)).getLayoutParams().height=23;
((ImageView)findViewById(R.id.imgview1)).getLayoutParams().width=23;
((ImageView)findViewById(R.id.imgview2)).getLayoutParams().height=LayoutParams.WRAP_CONTENT;
((ImageView)findViewById(R.id.imgview2)).getLayoutParams().width=LayoutParams.WRAP_CONTENT;
but in view when i touch any editText field then changes apply
((ImageView)findViewById(R.id.imgview2)).invalidate();
((ImageView)findViewById(R.id.imgview2)).refreshDrawableState();
and this isn't working too
((ImageView)findViewById(R.id.imgview1)).setLayoutParams(new LayoutParams(23,23));
((ImageView)findViewById(R.id.imgview2)).setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
by above statements my problem isn't solved

我认为问题在于，当您调用 getLayoutParams() 时，您会收到不可变的参数对象。考虑类似
setLayoutParamams(new LayoutParams(...))I think the issue is that when you call
getLayoutParams()you receive and immutable param object. Consider something likesetLayoutParamams(new LayoutParams(...))
